About Beijing Shouxi Zhixin Technology Co., Ltd. - Electric Components Supplier in China

Beijing Shouxi Zhixin Technology Co., Ltd. is based in Beijing, China and currently lists ten active electric component products. The catalogue focuses on semiconductor devices, specifically reverse‑engineered micro‑controller units (MCUs) from the STM32 family and a series of MC56F chips, with product titles such as "STM32F100R4 MCU Reverse" and "MC56F8006 Chip Crack". Two entries include explicit customs data: the STM32F100C8 MCU Reverse and the MC56F8006/MCF56F8002 Chip Crack are classified under HS code 8542.31 and are described as semiconductor silicon die with molded plastic housing or copper lead‑frame packaging respectively. The remaining eight items are listed without HS codes but fall within the same electronic integrated circuit category.

The supplier’s product set covers a range of 32‑bit ARM Cortex‑M0 micro‑controllers and mixed‑signal MC56F family chips, all presented as reverse‑engineered or cracked silicon dies. The catalogue does not provide additional specifications such as clock speed or package type, but each entry is identified by its official part number, indicating that buyers can match these units to standard datasheets for the original devices.

Product Range and Specialties of Beijing Shouxi Zhixin Technology Co., Ltd.

The catalogue contains four STM32F100 series MCU reverses (R6, R4, CB, C6, C8) and five MC56F series chip cracks (MC56F832X/812X, MC56F803X, MC56F802X, MC56F8006/MCF56F8002, MC56F801X). In the semiconductor industry, STM32F100 devices are 32‑bit ARM Cortex‑M0 cores typically rated at 48 MHz, offered in LQFP or UFQFPN packages, and classified under the integrated circuit HS heading 8542.31. MC56F chips belong to the Freescale (now NXP) ColdFire family, commonly used in automotive and industrial control, and also fall under HS 8542.31. Standard industry grades for such components include RoHS‑compliant, lead‑free, and IEC‑60730‑type reliability classifications. Buyers often request data sheets that list operating voltage (e.g., 2.0‑3.6 V), pin count (32‑64 pins), and performance metrics such as flash memory size and peripheral sets.

Trade and Export Information - Beijing Shouxi Zhixin Technology Co., Ltd.

China is one of the world’s largest exporters of electronic integrated circuits, and goods classified under HS 8542.31 are routinely shipped to North America, the European Union, and Southeast Asian manufacturing hubs. Export shipments of semiconductor dies are generally packed in anti‑static bags, reel‑to‑reel trays, or bulk trays within sealed cartons, and are transported in 20‑ft or 40‑ft containers under CIF or DDP terms. Importers commonly require certifications such as CE, UL, FCC, RoHS, and REACH compliance, as well as a Declaration of Conformity and test reports confirming functionality and environmental limits. Chinese exporters also follow the Ministry of Commerce’s export control regulations, which may involve electronic export licenses for dual‑use components.

Sourcing from Beijing Shouxi Zhixin Technology Co., Ltd. - Buyer Guidance

When sourcing from Beijing Shouxi Zhixin Technology, buyers should request the original device datasheet, a functional test report for the reverse‑engineered die, and RoHS/REACH compliance certificates for the specific part. Verification of the material description (silicon die with molded plastic housing or copper lead‑frame packaging) should be cross‑checked against the supplied HS code 8542.31 to ensure correct tariff treatment. Typical minimum order quantities for reverse‑engineered silicon dies range from 1,000 to 5,000 units, with lead times of four to six weeks after sample approval and receipt of required documentation.

What types of electric components are listed in the supplier’s catalogue?

The catalogue lists reverse‑engineered STM32F100 series micro‑controllers and cracked MC56F family chips, totaling ten distinct product entries.

Which HS code applies to the semiconductor items in the catalogue?

Two products are explicitly assigned HS code 8542.31, which covers electronic integrated circuits. The remaining items fall within the same HS heading based on their description as semiconductor dies.

What certifications should a buyer request for these semiconductor products?

Buyers should obtain RoHS and REACH compliance certificates, as well as any CE, UL, or FCC declarations that the supplier can provide for the specific die.

How are these semiconductor dies typically packaged for export?

Standard export packaging includes anti‑static bags, reel‑to‑reel trays, or bulk trays placed in sealed cartons, often within 20‑ft or 40‑ft containers.

What are typical minimum order quantities and lead times for these items?

Industry practice for reverse‑engineered silicon dies is a minimum order of 1,000 units, with a typical lead time of four to six weeks after sample acceptance.

How can a buyer request a sample of a specific MCU reverse?

The buyer should specify the exact product name (e.g., "STM32F100C8 MCU Reverse"), indicate the desired sample quantity, and ask for a functional test report and material certification before placing a full order.
